I used the 15 mm bit to fix a broken Ikea dresser. The crossbars broke during moving and I wanted to replace the crummy particle board with pine between the drawers. This forester bit worked great for drilling out the holes for the cam locks. I plan on purchasing more sizes later on as I need them (good-bye H.F. bits).

Just remember to use the proper drilling speed on your drill press and to not rush the cut. The Rockler promo video for these bits does a good job showing the capability of these bits.

I drill holes for tea candles in a variety of woods, including white birch and cherry. My 1 1/2" bit fit some of the tea candles but some, including the LED tea candles were slightly over 1 1/2" . The 40 mm bit (1.57") did the trick. Now any tea candle will fit in the hole. Not tight but loose. Just right.

I purchased 2 metric forstner bits a couple weeks ago. They were just what I needed. I had to make a hole to fit dowels I purchased from a hardware store. The standard forstner bits left the hole to loose. The metric were just under size enough to allow a tighter fit. Also I know I can used them on other projects because most related bolts and screws now come in metric form.

If you ever buy Rubbermaid pre cut closet shelving units, and have to shorten the shelves, you would need to redrill fastener holes, and they're metric. I only needed it for a dozen holes, but it was the perfect size for the project.

Regarding the 25mm bit -- it has an 8mm shank, not 3/8". I let Rockler know 9 days ago, but the website hasn't been updated. It wouldn't have been a big deal, but in the same order I purchased a bit extender. That, of course, only accepts 3/8" shanks. Not happy about the whole deal. On the plus side, the bit seemed razor sharp to the touch.

This is the worst bit I’ve ever gotten from Rockler. It was so dull that it took about 10 minutes to drill one hole 1/2” deep into Poplar. Thankfully I only had to do 4 holes for the two flipper doors. After the first hole I sharpened it with my router bit diamond stone and that helped some. Luckily all the other doors I did use a 35mm pocket.

I can only assume the 35mm Carbide Forstner Bit 46532 was machined off-center in some way since it made my drill press chuck wobble so much so as to create an oval hole the first time I used it. I borrowed a similar bit from my son and had no problem. In any case, it will be on its way back tomorrow for a refund.
